e) Using eyebolts with washer/nuts (not provided),
rig casing (1170) upper flange to overhead
hoist. Raise casing to a vertical position
directly over pump shaft. Apply a layer of
“gasket eliminator” (See point 10.3) to upper
flange of suction head (1130). Carefully lower
casing over end of pump shaft until casing is
resting in position on suction head. Install
casing to suction head bolting (6579) and
torque. Do not unhook rigging attached to
eyebolts in casing upper flange.
NOTE
Be sure case bearing (3312) was fitted previously
into case and during assembly bearings do not
“Hang –up” when passing over shafts.
f) Using rigging attached to eyebolts in casing
(1170) upper flange. Lift pump assembly
slightly and install sling (provided by customer)
around lower portion of the casing. Rig sling to
an auxiliary hoist. Using both hoist lift pump
assembly from blocking and maneuver into a
horizontal position on blocking on the floor.
NOTE
At no time should the pump assembly be rotated on
the suction head (1130) or strikes the floor or other
object.
g) Be sure casing and pump shaft are properly
positioned on blocking on the floor (horizontally
leveled).
h) Install sling along upper shaft (2130) and rig to
an overhead hoist. Install shaft coupling (7238)
over lower end of upper shaft. Slide shaft
coupling beyond keyway for shaft coupling key.
Lift upper shaft in a horizontal position taking
care that shaft coupling (7238) does not drop
off upper shaft. Place upper shaft into position
as close as possible to pump shaft (2110)
without hitting them together. Install split ring
halves (7415) which locks the upper shaft to
pump end shaft. Install shaft coupling keys into
keyways of both shafts. Slide shaft coupling
down over keys and split ring until the shaft
coupling comes in contact with gib key. Install
the socket screw bolting between shaft
coupling and key. Tighten and torque.
NOTE
Upper shaft (2130) must be supported on blocking
before removing rigging from overhead hoist (do
not hung it).
i)
Using the overhead hoist, lift the outer column
(1350) from blocking on the floor in a horizontal
position. Apply layer of “gasket eliminator” to
upper flange of casing (1170). Install outer
column over coupling end of upper shaft and
into position against upper flange of casing.
Install bolting between outer column and
casing and torque them.
NOTE
Blocking under upper shaft (2130) will have to be
removed and reinstalled as outer column (1350) is
being installed.
j)
Install slings (provided by customer) through
“windows” of the discharge head (1371) and rig
to an overhead hoist. Lift the discharge head
from blocking on the floor in a horizontal
position. Apply a layer of “gasket eliminator”
on upper flange of outer column (1350). Install
discharge head over coupling end of upper
shaft and into position on outer column. Install
bolting between discharge head and outer
column and torque them.
k) Install “O” ring (4610) and stuffing box
extension journal sleeve (4610) over upper end
of upper shaft (2130) and position on key
(6733) and retaining ring at the sleeve end.
l)
Rig and install stuffing box extension (4110) on
discharge head. Install stuffing box extension
to discharge head bolting and torque them.
m) Install chains or slings (provided by customer)
through big lifting lugs in discharge head
(1371) and around casing (1170) and rig to an
overhead hoist. Using both hoists, carefully
raise the unit to a vertical position over the pit,
taking care not to rotate or support the
assembly on suction head (1130). Remove
sling around casing. Lower unit into pit unit until
the discharge head flange rests on the
soleplate (6140) and bolting.
n) Check pump / motor direction of rotation as
described on point 5.3
o) If mechanical seal is supplied, install seal box
and seal cartridge – without tight set screws of
drive collar
p) Install pump half coupling, adjusting nut and
motor with its half coupling and make
alignment according point 4.5.2
q) Adjust rotor setting according point 5.5
r) Install back ring (4132), packing (4120) and
packing gland, see point 5.7.1 (if mechanical
seal is supplied, tight set screws of drive collar)
s) Install auxiliary piping and wiring. Install air
release valve (if used). Install coupling guards
on “windows” in the pump discharge head.
